The famous Tatlock marble quarry is owned by the Swiss mineral company OMYA. It produces calcium carbonate derived from natural marble (or limestone) rock formation. Calcium carbonate is used as filler in things like paint, plastics, paper and toothpaste. The Tatlock quarry is about 900 meters long, 400 meters wide and 110 meters deep.
